アイドリングストップ信号表示装置

Idling stop signal indication device

Abstract

PROBLEM TO BE SOLVED: To promote movement of 'stop idling', by asking a driver to stop an engine during the time such as stopping at a red light or in front of a crossing bar, and then by notifying the driver of the engine start timing. SOLUTION: This idling stop signal indication device comprises at least: a signal display portion 15 for displaying an indication of asking the driver to stop the engine and then an indication of starting of the engine; and a signal control portion 13 that determines a time where the driver should stop the engine depending on an input signal to make the signal display portion 15 display the indication of promoting the driver to stop the engine, and then determines a time of starting the engine to make the signal display portion display the indication of asking the driver to start the engine. In a case where the idling stop signal indication device is connected to a traffic signal control equipment 2, the signal control portion controls so that the signal display portion displays a first indication of stopping the engine, a second indication of holding a state of the engine, and a third indication of starting the engine sequentially, when the length of the red light immediately before repeating the red light and a blank period in input information is not less than a reference value. Further, the signal control portion 13 controls so that the signal display portion 15 displays only the second indication when the length of the red lights immediately before repeating the red light and the blank period in input information is not more than a reference value.
(57)【要約】 【課題】 赤信号表示中、踏切遮断竿降下中などに、エ ンジンの停止を促し、エンジン始動時期を知らせて「ア イドリングストップ」運動を普及させる。 【解決手段】 少なくともエンジンの停止を促す表示、 エンジンの始動を促す表示を行う信号表示部(15) と、入力信号に基づいてエンジンの停止すべき時間を判 定し信号表示部にエンジンの停止を促す表示を行わせ、 エンジンの始動すべき時間を判定してエンジンの始動を 促す表示をさせる信号制御部(13)とを備えている。 交通信号制御器機(2)に接続される場合は、信号制御 部は信号表示部に対し、入力情報の赤信号と空白の繰り 返しの直前の赤信号の長さが基準値以上の場合、エンジ ン停止の第1の表示と、続くエンジン状態そのままの第 2の表示と、続くエンジン始動の第3の表示とを順次行 うよう制御し、直前の赤信号の長さが前記基準値以下の 場合、前記第2の表示のみを表示するよう制御する。
